Denis Diderot is regarded as one of the brightest minds of the European Enlightenment, if not of the entire history of Western thought. He became well-known and famous as an encyclopedist, philosopher, publicist, writer, playwright, art and music scholar, and ultimately as a pioneer of democracy. Lessing referred to him as a cloud-maker and a sage of the world, Nietzsche as the first spirit of the new France, and Schiller praised his thoughts as sparks of light. On the occasion of his 300th birthday in 2013, Werner Raupp takes a journey through Diderot's life and work, creating a colorful mosaic of 100 concise thoughts from the philosopher, ranging from short aphorisms to longer excerpts from novels and letters that inspire reflection and further thought.
